This is one of a number of reasons a lot of people just buy low-cost, diversified mutual funds like Vanguard's 500 Index Fund or Total Stock Market Index Fund. You just put in money and everything else is taken care of. Although I play around with some stocks for fun, all my retirement funds are in Vanguard's Total Stock Market Index Fund. It's a one-stop shop.
